Yes! but only if you have or had a subscription with us. If you'd like to add additional Flavor Boosts as part of your monthly subscription plan then simply log into your profile at Gainful.com/me and navigate to the "Subscription" tab. Then, under the "Add-Ons" section you can select as many additional flavors as you'd like. These are $ 3 a carton (each carton contains 7 individual Flavor Boosts).
